Decoding single-crystal lithium growth through solid electrolyte interphase omics.

ABSTRACT: Accurately understanding the impact of solid electrolyte interphase (SEI) on lithium deposition is critical for high-energy lithium metal batteries. Yet traditional strategies, focusing solely on isolated components, fail to capture multi-constituent synergies and underlying mechanisms. To address this challenge, we introduce the concept of SEI omics and establish a dataset of cryogenic transmission electron microscopy images combined with co-localized component information. By integrating interpretable machine learning and physics-based feature selection, we decoupled the roles of SEI constituents, revealing that higher N/S/P/F content and reduced O in the SEI improve lithium deposition. Combined density functional theory and electrochemical phase-field modeling uncovered multi-scale effe
